What does AHU-FC06 mean?
The fraction of outside air being introduced doesn't match what the operating state calls for.
Why does it matter?
Either under-ventilating (IAQ concern) or over-ventilating (energy waste). Both have measurable impact.
What should you do?
Verify OA damper response to commands. Check whether damper command is being clamped by a high/low limit. Inspect blade leakage.
This is a diagnostic rule: Energy Agent surfaces and ranks it as a reliability problem and claims no dollar savings for it, by design.
